IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 42,417, dated April 19,1864.

To @ZZ whom it may concern.-

every respect to the globe-valve yD in the 'Be it known that I, JAMESToMLlNsoN, of chamber C.

had to the accompanying drawing, making i a part ot' this specification,and representing a longitudinal vertical section of a pump constructedaccording to my invention.

The object of this invention is to construct The valve G closes downupon the seat d, and a fender, e, in the upper part ofthe valvechamber Cprevents it from rising to such a i height that it interferes with theupward pas l sage of the water.

; H is the ascension-pipe, which screws in the y upper end ofthe cvlinder E, and connected by l means of a pivot,f,and link g with thehandlever I. This hand-lever has its fulcrum on a i pivot, h, in aforked standard, J, which rises a pump with the least possible amountof; from the pump-stock K, and said pumpstock valvesurface and with along stroke, so that l is intended to represent the trunk of a tree, thesame can be used in deep wells and com with roots to bolt down to theplank on the paratively little power is required for its opertop of thewellcurb. The upper end of the ation.

The nature of my invention and its peculiar advantageswill be readilyunderstood from the following description:

A represents a stationery piston, cast or otherwise provided with aange,a, and bolted on the upright post or scantling B, which extends down tothe bottom of the well. This piston is perforated throughout its wholelength and is furnished with a chamber, C, to contain the globe-valve D,of india-rubber or other suitable material. This valve closes down uponthe seat b, and when it rises it strikes the fender c, so as to preventit closing' Q the upward passage and to allow the water to I ascendfreely through the perforated piston.

The outside surf-.ice of the piston is turned oft' perfectly round andparallel from its upper end down to the valvechamber, and it is fittednicely into the movable cylinder E, which may be provided with suitablepacking, so that it works up and down air-tight on the piston.

Said cylinder terminates at its upper end in a chamber, F, similar tothe valve chamber() atthe bottom end of the piston, and this chamber isoccupied by a globe-valve G, of indiarubber or other suitable material,similar in ascension-pipe is curved downward so that it forms a spoutfrom which the water will be conveniently received in a suitable vessel.If the handle I is depressed, the cylinder E rises and the valve Gcloses. The air in the hollow piston is raretied, the valve D opens, andthe Waterfrom b elow,impelled bythe atmospheric pressure, rises into thehollow piston` On raising the handle the cylinder E is depressed, thevalve D closes, and the water contained in the hollow piston opens thevalve G and rises through the ascension'pipe H to the spout.

This pump is very simple in its construction, it can be made cheap, andit works easy l in deep wells.

i What I claim as new, and desire to secure by Letters Patent, is-

The stationary piston A, with globular l chamber O and valve D, incombination with i the reciprocating-cylinder E, globular chaml ber F,valve G, ascension pipe H, and handlever I, all constructed andoperating,` in the manner and for the purpose herein shown anddescribed.
